The end pressure exerted by the Workman upsets the material of the neck, causing it to fill the mold, and leaves a lip or end to the neck exactly true in relation to its axis and length with the segments formed in the neck. Upon opening the implement by relaxing the grasp on the handles the bottle-neck is liberated anddischarged from the mold. Having described my invention, what I claim isg 1. In a tool for finishing bottle-necks with external segmental projections thereon, a rotatable mold adapted to inclose the end of the bottle neck having segmental recesses opening to the rim of the mold in combination with expansible and contractible jaws and connected handles for holding said jaws in closed position over the mold and bottleneck substantially as set forth.

2. In a tool for finishing bottle-necks a rotatable mold adapted to surround the neck of a bottle and having recesses therein for molding projections on the bottle-neck, a tapering non-rotatable fluted plug in combination with shouldered jaws adapted to close over the mold and connected handles for opening and closing said jaws as set forth.
